Abstract

Control of a packet communications network in a fixed network used by a mobile communications network is provided. (1) A communication hold mode is set for a user when the traffic volume of the user's transmission or reception of a packet per fixed time period is less than a predetermined value. The communication hold mode is defined as ''although the network resources are released once, a mobile station and a gateway center at an interface with an external network behave to the user side and the external side as though the communication hold mode were maintained''. (2) When the user in the communication hold mode restarts the transmission of a packet, the mobile station automatically carries out a recall processing without the intervention of the user, and reestablishes the communication up to the gateway center. (3) When the gateway center restarts receiving a packet to the user in the communication hold mode, the gateway center carries out the incoming recall processing without the intervention of the external network, and reestablishes the communication all the way to the mobile station. (4) To accomplish the incoming recall processing, the mobile station makes a location registration when it roams across location registration areas after a transition into the communication hold mode.

Description

Packet communication network

The present invention relates to be used for the packet communication network of transmitting and receiving packet data, specially refer to the packet communication network in the mobile communication.

In general, provide the expense of the business enterprice sector of packet communication services, be not that basis was charged with corresponding communication time turn-on time, but carry out and the corresponding charge according to quantity system of grouping information amount for packet communication services.

In other words, if when packet communication services begins, each Packet Switch Node place in net, the table of the path of destination being sent in decision according to the address of minute group of recipients writes processing, then just needn't do special processing when the actual arrival of the grouping with this appropriate address.Like this, even carry out charge according to quantity system, also be worthwhile to the business enterprice sector that this service is provided.

On the other hand, the user Once you begin communicates by letter and after having established the communication route, just can not charge unless send out grouping.Therefore, when carrying out the communication of low information density intermittently, to set the grouping route earlier usually.Like this, by setting route, just needn't communicate setting usually, have the advantage that to receive and dispatch grouping in any time that information produces reposefully the transmitting-receiving rank of information.

But after setting the grouping route, will form the part of occupying grouping route network resource by the route of such setting as mentioned above regularly.This resource of occupying for example can be the resource that is used to keep transmission quality.Yet, for not becoming the object of charge because of setting resource in the net that the grouping route occupies.

Suppose that other users also communicate after this and set and when resource does not have idle component in its net, will become the state (being called busy condition) that can not communicate.When using certain interval resource jointly for (not specific) most users, in order to allow to carry out packet communication services simultaneously to all users, the usually necessary corresponding interval interior resource with each user, the resource that this has just become necessary preparation to expand prepared.This can become very big burden economically for telecommunications services division, and when having the time zone of communication band in unavailable late into the night, just becomes useless resource naturally.

In addition, when in mobile communication, providing packet communication services,, add mobility control outside the processing again with regard to sending in above-mentioned grouping because the user moves.To follow the trail of moving of travelling carriage in other words, the Radio Basic Station that communicates with travelling carriage be done cutting of hand-off process move processing.When in mobile communication, providing packet communication services, though wish to increase again corresponding to the charge share of amount of movement so that cost recovery with respect to charge according to quantity, concerning the user, because this with the charging method difference that fixed network generally provides, is difficult to receive.

Like this, when packet communication services is provided, do not carrying out keeping route under the charge state with respect to the user, also promptly the packet communication user is only made communication setting, the transmitting-receiving of in fact grouping is not existed or has only routing state under the minute quantity situation, keep as low cost how, just become a problem to be solved.

Particularly when mobile communication, just had simultaneously and shifted, one side is carried out the problem that route is kept.

At this moment, when the user carried out data communication, one side guaranteed to provide the communication speed of necessity to greatest extent actually, and one side can be distributed to resource in the net more user and economic communication service is provided, and also becomes problem of the present invention.

In order to address the above problem, feature of the present invention is, in the resource management of packet communication network, establish the traffic of back monitoring user in communication setting, when satisfying existing fixed guard condition, by with the user's communications state as the communication reserved state, discharge at least a portion of the resource of distributing to the user, under the communication reserved state, behind the beginning packet communication, promptly be returned to communications status.

Above-mentioned communication reserved state is that transmission line resource and via node resource discharge in certain interval that the user is connected, and resource above-mentioned interval in is become can be by the state of other users' uses.

Aforementioned guard condition from communications status to the communication reserved state is not have the transmitting-receiving of user grouping in fiducial time.

Each user of above-mentioned control survey does not does not receive and dispatch the time of grouping and sends out the time that this measures; The setting of above-mentioned reserved state is after receiving the aforementioned Measuring Time that is sent out, itself and predetermined fiducial time are compared, to grasp the situation that the above-mentioned time of measuring surpasses fiducial time, when knowing above fiducial time, promptly send instruction to user resource allocation, according to this instruction, just can discharge the resource of distributing to the user.The release of described resource also can be to change resource status according to the time.

When changing resource status, also can have the priority allocation of state get to(for) the user of reserved state above-mentioned according to the time.

The setting of above-mentioned reserved state can also be change fiducial time.At this moment, the change of fiducial time for example also can be logined, store each user the determined time, and reference is to carrying out the fiducial time of each user storage.

The user also can specify fiducial time, measures the frequency that each user utilizes communication, sets fiducial time and can calculate according to this frequency.

Also frequent resource utilization in the monitoring network is set fiducial time according to utilization rate.

Release to above-mentioned resource can also be equipped with release procedure and the control regularly of each user being guaranteed resource.

Above-mentioned release controlled step can have the feature that discharges control by preset program and timing.

In addition, in above-mentioned communication reserved state, for connecting from communications status one side when confirming, node of this communication reserved state interval endpoint has the signal that expression is connected and does simulation and return and connect the device of confirming.

Under above-mentioned communication reserved state, the node of communication reserved state interval endpoint sends the connection confirmation signal that affirmation has connected with respect to communications status one side.When the node of above-mentioned end points can not be confirmed to connect by sending out aforementioned connection confirmation signal, i.e. abort communication.

When turning back to communications status, adopting common transmitting/receiving program from the communication reserved state.

When being transformed into reserved state, can be in advance the program that is used for returning and routing table be stored in the node of the reserved state interval endpoint of communicating by letter.

Above-mentioned packet communication network also can be the mobile network.At this moment, under above-mentioned communication reserved state, the login of the position of travelling carriage can similarly be carried out with common wait accepting state.

Have, when user notification moves, can utilize information management and subscriber-related information before moving, according to guaranteeing resource in the network with subscriber-related information, and unnecessary relevant user's information is gone up in the deletion management, discharges to move preceding resource.

The working of an invention form

(form of implementation 1)

As form of implementation 1, the situation of carrying out packet communication between mobile subscriber and other network users is described at first.

Fig. 1 illustrates network configuration.MS is a travelling carriage among Fig. 1, and BTS is a Radio Basic Station, and MSC is board (relay station), and SCP is a service control device.

Be connected with a plurality of packet communicate terminals (user) in the travelling carriage, in a travelling carriage, can carry out multichannel communication simultaneously.When being used for packet communication, between travelling carriage and user terminal, need adapter sometimes, but can be included its a kind of function as travelling carriage at this.Radio Basic Station BTS11～BTS1N, BTS21～BTS2N, BTS31～BTS3N provide the radio corresponding to lane place LA1, LA2, LA3 to insert respectively.Board MSC1, MSC2 at random accommodate these Radio Basic Stations.Board MSC3, MCS4 carry out relaying to the information that board MSC1, MSC2 compile.Board MSC5, MSC6 can realize the gateway function with other networks 1,2.This is a same device on the one hand basically though each board is carrying out information exchange, corresponding to the network function structure, can realize functions such as user MSC, relay MSC.Also can merge in the board according to the multiple function of structure with these boards.Service control device SCP has stored the user profile that is used to serve control, the positional information of travelling carriage etc.

Referring now to Fig. 2, comes diagrammatic illustration the present invention.Among Fig. 2, DTE is the device (for example personal computer etc.) that carries out the data communication that is connected with mobile machine MS.BTS-T is a Radio Basic Station, and MSC-L is a private branch switchboard, and MSC-T is a tandem switching, MSC-G be used for net that other networks are connected between docking station (gate station).The structure of Fig. 2 is the formations such as node of the formation communication route that extracts in the structure of Fig. 1.

In such structure, mobile station MS has been set the communication route of carrying out packet switching by between Radio Basic Station BTS etc. and other networks.The state of this communication route has the reserved state of communicating by letter with (b) of (a) communication setting state among Fig. 2.Describe below at this point.

(1) within a certain period of time, there is not the user of the above grouping transmitting-receiving of certain traffic, is set at the communication reserved state.So-called communication reserved state is meant " resource is discharged temporarily in the net, and docking station carries out work between the net between travelling carriage and other networks, just still keeps the communication setting state as user side and other network sides ".

(2) user for the communication reserved state begins the situation of dividing into groups to send once more, and travelling carriage carries out connection processing (for example recall) again when not having the user to operate, be reset to the communication setting state of docking station between net.

When (3) between net, beginning branch group of received with respect to the user of communication reserved state in the docking station again, net the nothing of a docking station and other networks and control again connection processing (for example receive again and handle), be set to the communication setting state of travelling carriage again.

(4) in order to realize the connection processing again (for example receive again and handle) in (3), travelling carriage carries out the position login when the spanning position logon area after transforming to the communication reserved state.

Get back to Fig. 1, the operation of general description above describing in detail.

(travelling carriage transmission)

At first describe travelling carriage and send to the communication setting operation that connects switching station between net.

The Radio Basic Station (for example BTS11) of mobile station MS 1 by covering sends the transmission signal that is used to begin packet communication with respect to user's relay station (for example MSC1).At user's relay station MSC1, analyze and send signal, analyze and judgement reception destination.Then, be when being included in the external network 1 for example when receiving the destination, can obtain and be set to the communication setting that is connected relay station MSC5 between net, be i.e. communication path (radio communication road, user path, relay route etc.) and communication process resource (shifting resources such as trunk line, service processing trunk line, transaction).

Receive the analysis of destination and judge and to analyze by the position data that is used to analyze in user's relay station, also can be undertaken by the inquiry that the position data that is used in the service control device analyze is carried out user's relay station.

Connect between net relay station MSC5 solve with external network 1 in relative net between the communicating by letter of connected node, connect the communication setting (also can carry out) of the interior purpose object of connected node and external network between relay station and the corresponding net of other networks 1 between netting from the relaying of external network 1 to the 3rd network.

In addition, connecting between net between relay station MSC5 and external network 1 corresponding net before the connected node, by choosing the part of the common grouping address of determining grouping address corresponding or a collection of user group with the specific user, earlier internetwork communication setting is made stable setting, also can only carry out the communication setting (example as the grouping address has IP grouping address, E-mail address and domain name etc.) in the network when user makes communication setting.

By above operation, established the communication path and the resource of handling usefulness of the other user under the administration from the user of mobile station to the external network, just can receive and dispatch grouping mutually subsequently with particular address.

In this form of implementation, though do not do detailed especially description for the adding method of this address, the route selection method of employing address, but within network, give this address, and method of routing can roughly be divided into employing travelling carriage-to the situation of docking station unique address between net and adopt as heir the method for a plurality of addresses.

But no matter be under which kind of situation, among relay station, Radio Basic Station, the address that the user is used and the corresponding relation of the path of sending to the destination and channel etc. can not change under the table management.In addition, depend on load mode, use the different value of situation that adopts same value with the address of transmitter side and receiver side sometimes, this is that the table of transmitter side and receiver side is due to managed together or the problem of managing independently.Can both be corresponding in this form of implementation to any situation wherein.

Below will be by communicating the setting in path, the example of the grouping routing table that generates in each grouping transmission, switching node (travelling carriage, radio base station, each relay station) is shown in Fig. 3.With the travelling carriage is example, travelling carriage accepts to have the grouping of different grouping address from a plurality of users, according to input point/channel and input grouping address, the radio channel of differentiating output used grouping address, radio interval when Input Address changes, travelling carriage is a reference table, to import the grouping address and be rewritten as output grouping address (send with radio channel when only being grouping for its user when using,, can omit) because this grouping address becomes tediously long in the radio interval.

At the radio base station platform, judge outlet line according to input with radio channel and input grouping address, in case of necessity, send to outlet line after being rewritten as OPADD again.Then, user's relay station, relaying relay station are selected route similarly, finally are transferred to external network from connecting relay station between net.

(travelling carriage reception)

In the travelling carriage that the user connects, in order to receive the received signal that packet communication begins usefulness, travelling carriage usually carries out the position login, the lane place under the travelling carriage need be sent to network one side.Therefore, the information that travelling carriage is reported according to Radio Basic Station, judge that travelling carriage enters new lane place after, Radio Basic Station, the relay station that promptly passes through to be covered, service control device is carried out up-to-date band of position login.

This moment, the user similarly sent the own travelling carriage that is connected to service control device in advance, received login.

Receive under the completed prerequisite of login in login of the position of the travelling carriage that the user connects and user, describe below with respect to connecting relay station MSC5 sends information to the user from external network 1 situation between net.

Connect the communication setting that relay station MSC5 carries out connecting between communication, net with connected node between the relative net of external network 1 connected node between the relay station net relative with external network between net.In addition, between the relative net that connects relay station MSC5 and external network 1 between net between the connected node,, can omit this internetwork communication setting and handle for the foregoing situation of stably choosing and having determined the address.Have again, also the reception of starting as received signal from the grouping that external network received in the network can be handled in this case.

Carry out then setting to user's communications from connecting relay station MSC5 between net, the user then carries out paging in order whether to judge in the coverage of Radio Basic Station.

In order to carry out paging, connect relay station MSC5 notification service control device SCP between net with reception user identifier that includes the received signal that is received from external network 1 or the address of choosing definite grouping in advance.Service control device SCP is according to the identifier that receives the user or chosen definite grouping address, with reference to the reception logging status that receives the user, judges to receive the travelling carriage that the user connected, and according to the position logging status of travelling carriage, specifically determines the lane place again.From the Radio Basic Station group paging receiving mobile in collecting position district, as the Radio Basic Station in the area of coverage, identical during with transmission then the Radio Basic Station that has travelling carriage to reply, carry out being connected between travelling carriage and net the communication setting between relay station.The transmitting-receiving that can divide into groups then.

(transfer behind the communication setting)

In transmitting-receiving, after communication setting is finished, just can constantly divide into groups to receive and dispatch between mobile subscriber and the other user arbitrarily.Under this state, the mobile subscriber for example Radio Basic Station BTS11 in the coverage moves to Radio Basic Station BTS12 direction, shifts to Radio Basic Station BTS12 to realizing transfer processing in coverage from Radio Basic Station BTS11.This transfer processing has the various methodologies by radio method and transfer moving method etc.

Though do not determine to use metastasis treating method in the present invention especially, but actually, the transmitting-receiving that surpasses certain traffic between mobile subscriber and the other user within a certain period of time is limited, carry out this transfer processing, just can upgrade Radio Basic Station and Route Selection and route in the coverage.

(transfer) to the communication reserved state

Connect between travelling carriage or net relay station (or being connected relay station between travelling carriage and net) preferably the packet traffic to the user monitor especially, in certain regular hour, when the grouping more than not having certain traffic is received and dispatched (when for example not having the transmitting-receiving more than 1 grouping in 10 minutes), i.e. decision is transformed into the communication reserved state (still, above-mentioned supervision and decision can be the nodes that has in the route of the selection of grouping, also can be to connect relay station node in addition between travelling carriage, net).

After decision was transformed into the communication reserved state, decision was converted to the node of communication reserved state, was issued to the triggering signal of communication reserved state, according to this triggering signal, removed communication and set outside the required least resource again, discharged the whole resources in the net.

In this form of implementation, can maintenance communication for making the external portion of user network, need guarantee the resource of minimum limit, so that when the communication reserved state is returned, do not need to communicate again and set by user or external network.Setting necessary bottom line resource again as being used for communicating by letter for example can enumerate as follows:

Imposing a condition of the customer-side of the grouping routing table in the travelling carriage;

The resource that connects between net outside the imposing a condition of external network aspect of the grouping routing table in the relay station can discharge.

When using this resource, the docking station aspect needs and exhales the maintenance function that receives parameter more again between travelling carriage aspect and net.Perhaps can be used for service control device SCP to this maintenance function.When docking station side maintains the table of storage above-mentioned parameter between travelling carriage side/net, have and exhale/receive, docking station side then is necessary the table that keeps above-mentioned among both between travelling carriage side/net.For this reason, when transforming to reserved state, be the table that carries out judging a side, according to concrete situation and the other side (a relative side) associative transformation, transmission to the reserved state conversion.

Then, in is connected between travelling carriage and net relay station monitor the user communicate reservation begin again packet communication (still, when travelling carriage with net between be connected relay station in addition as the reserved area between the time, then with the node supervision at two ends between this reserved area).

(the position login in the communication reserved state)

After the conversion of communication reserved state, travelling carriage is identical with the state that does not communicate setting, when travelling carriage enters in the new lane place, carries out up-to-date lane place login with respect to service control device.Here used position login mode also can be got based on being the base position coding with time or logining based on the position of distance beyond the login of the position in place.

(in the communication reserved state to the processing of connectivity confirmation signal)

In communication, exist internuncial signal of confirming that the user connects.

In communication keeps, for above-mentioned signal, for the signal from the portable terminal that is connected with travelling carriage is by travelling carriage, and be by docking station, the simulation correspondence to processing, return from this class signal of affirmation signal of distant terminal respectively between net for external network one side's terminal.

On the contrary, travelling carriage is with respect to the terminal that connects, and docking station all has the function that can send out the connectivity confirmation signal whether this each terminal connect with respect to the terminal of external network side between the net of mobile network aspect.

Utilize above-mentioned confirmation signal, can carry out the internuncial affirmation of terminal.In the time connectivity can not being confirmed, just become interruption according to this connectivity confirmation signal.In case in have no progeny owing to cut off, just transmit end of communication signal to docking station between net or from docking station between netting to travelling carriage from travelling carriage.At this moment, docking station promptly communicates end process with the side in reserved state still between travelling carriage or net.

(from the communication reserved state to connecting one again)

Travelling carriage detect communication keep in user when beginning grouping again and sending, carry out the connection again between the reserved area with this beginning again of dividing into groups to send as triggering.As realize this again an example of method of attachment be, adopt impose a condition (the discharging) of the user side of grouping routing table in the travelling carriage, proceed to the communication setting that connects relay station MSC5 between net according to sending identical program with travelling carriage.Thus, the user can be without operating the transmitting-receiving of dividing into groups especially.

(to connecting, they two again from reserved state)

Detect the reception user of communication in keeping when beginning the branch group of received again when connecting relay station between net, as triggering, carry out the connection again between the reserved area with this branch group of received again.As one of example of the method that realizes connecting again is according to receiving identical program with travelling carriage, between net, adopt in the docking station grouping routing table and external network aspect impose a condition (discharging), proceed to the communication setting of travelling carriage.Thus, external network is not done the transmitting-receiving that special control is divided into groups relatively.

In addition, in order to carry out thisly connecting, prerequisite is the more position login in the new traffic reserved state of travelling carriage again.

(from communication reserved state to sign off)

Docking station one side's connectivity confirmation signal between with respect to travelling carriage one side/net, when each terminal no response, communication promptly finishes.At this moment transmit end of communication signal to docking station between net or from docking station between net to travelling carriage from travelling carriage.At this moment, between travelling carriage one side or net docking station one side to still communicating end process reserved state one side (docking station one side between be netting during travelling carriage one side's no response is travelling carriage one side during the no response of network docking station).

Like this, terminal that is connected with travelling carriage and the terminal in the external network can effectively utilize line resource when carrying out packet communication.

(form of implementation 2)

(communication between mobile subscriber～mobile subscriber)

The example of communicating by letter between mobile subscriber and external network has been described in form of implementation 1, and this form of implementation will illustrate the communication between mobile subscriber～mobile subscriber.

Fig. 4 explanation is used to carry out the network configuration of communicating by letter between mobile subscriber～mobile subscriber.Fig. 4 has omitted the figure that connects relay station between net in Fig. 1, then there is same structure other aspects.

(travelling carriage transmitting-receiving)

Communication setting operation when mobile station MS 2 receives according to Fig. 4 illustrates mobile station MS 1 transmission below.

Travelling carriage 1 sends the transmission signal that is used to begin packet communication by radio base station (for example BTS11) in the coverage to the MSC1 of user tandem office.User's relay station MSC1 analyzes and sends signal, analyzes and judge to receive the destination.When receiving the destination and be the mobile subscriber, visit receives the destination whether in coverage LA to service control device SCP, in this LA, in order to judge that the reception mobile subscriber is in the coverage of which Radio Basic Station, carries out paging.

In order to carry out paging, user's relay station MSC-1 will be included in the identifier of the reception user in the transmission signal of acceptance, from sending user notification service control device SCP, the latter receives user's identifier according to terminating, with reference to the reception logging status that receives the user, judge that receiving the user connects travelling carriage, according to the position logging status of travelling carriage, determines the lane place again.From the Radio Basic Station group mobile paging station in collecting position district, the base station (for example BTS 31) of Radio Basic Station conduct in coverage that will have travelling carriage to reply sends the communication setting between mobile station MS 1～receiving mobile MS2 then.In the network configuration of Fig. 4, owing to circuit is arranged between the user's relay station that has compiled each Radio Basic Station in coverage, for example just can set the such communication path of mobile station MS 1～Radio Basic Station BTS11～trunk desk MSC1～trunk desk MSC2～Radio Basic Station BTS31～mobile station MS 2.After having set communication path in this wise, just can receive and dispatch grouping.

By having set communication path, at the transmission of each grouping, the grouping routing table that switching node (travelling carriage, Radio Basic Station, each relay station) is located to generate, then as in the form of implementation 1 with explanation that Fig. 3 did.

(transfer behind the communication setting)

Transfer behind the communication setting is identical with described in the form of implementation 1 then.In form of implementation 2, move because mobile station MS 1 and mobile station MS 2 are independent respectively, transfer processing is also handled in each mobile station MS 1 and MS2 respectively independently.

The following describes as the control of feature of the present invention is the control of reserved state.

(being converted to the communication reserved state)

Mobile station MS 1 or mobile station MS 2 (perhaps MS1 and MS2) monitor specific user's packet traffic, when grouping when transmitting-receiving that in certain certain hour, does not exist more than certain traffic, promptly the decision transform to communication reserved state (this decision if the grouping the Route Selection path in node, then the node outside the travelling carriage (relay station etc.) also is fine).

After decision transforms to the communication reserved state, the node that decision transforms to the communication reserved state promptly sends triggering signal to the communication reserved state, according to this triggering signal, removing is used to communicate by letter sets the resource of necessary minimum limit again, discharges all resources in the net.

Be used to communicate by letter and set necessary bottom line resource again and be set out in down:

The resource with outside the imposing a condition of user of grouping routing table can discharge among mobile station MS 1 and the MS2.

When using this resource, docking station side between mobile station side and net, the parameter that need exhale again/receive keeps function.Perhaps can be used for service control device SCP to this maintenance function.Docking station side between mobile station side/net keeps storing under the situation of above-mentioned parameter table, has to exhale/receiving function more again, connects the above-mentioned table of side two sides needs maintenance between mobile station side/net.For this reason, when transforming to reserved state, according to concrete situation, be incorporated into line translation, transmission to the table that carries out to reserved state conversion judgement aspect with the other side.

Subsequently, monitor that in mobile station MS 1 and mobile station MS 2 each user's who communicates reservation packet communication begins again.

(the position login in the communication reserved state)

After transforming to the communication reserved state, mobile station MS 1 is identical with form of implementation 1 with mobile station MS 2, is not doing under the communication setting state equally, when entering new lane place after moving, carries out up-to-date lane place login with respect to service control device.

(from the communication reserved state to connecting again)

The grouping that mobile station MS 1 or mobile station MS 2 detect the user of communication in keeping sends when beginning again, promptly divides into groups to send with this to begin to carry out connection again between the reserved area as triggering again.As realizing this example of method of attachment again, be according to receiving and dispatching identical program with travelling carriage, adopt the grouping routing table and impose a condition (discharging) user side in mobile station MS 1 or the mobile station MS 2, proceed to the communication setting of the travelling carriage of distant terminal.Can not do the transmitting-receiving of dividing into groups under the special control by each user thus.

In addition, in order to carry out above-mentionedly connecting again, more log on as prerequisite in the position in the new traffic reserved state with mobile station MS 1 and mobile station MS 2.

(from communication reserved state to sign off)

When the connectivity confirmation signal of connection side was not replied between each terminal is for mobile station side/net, communication promptly finished.At this moment transmit end of communication signal to the travelling carriage aspect from the travelling carriage aspect to docking station aspect net or from docking station aspect between net.At this moment, between travelling carriage or net docking station with still be in reserved state one side (when the travelling carriage no response during docking station no response be travelling carriage net between for docking station between netting) and communicate end process.

(to the applicability of fixing packet network)

In above-mentioned form of implementation, be just to be described with respect to the packet communication in the mobile radio communication of mobile communication, control but in fixing packet communication network, also can be set at the communication reserved state.At this moment, the control section of relevant above-mentioned position login is promptly unnecessary.

As mentioned above, in packet communication network, being set at the communication reserved state is in order to effectively utilize line resource.Describe the control of this communication reserved state below in detail.

At first when the user guarantees not do under the state of resources grouping transmitting-receiving, the release of resource is described with Fig. 5.

Fig. 5 is the structure chart of the invention process form in the packet communication network.At first explanation, when using this packet communication network, the net inner structure when dividing into groups to receive and dispatch between user terminal 1 and the communication counterpart terminal 2.

When measurement section 13,13 ' is measured user terminal 1 transmitting-receiving and time in when transmitting-receiving and send the time of measuring to comparing section 5.Measurement section 13,13 ' can be arranged at and constitute network node place interval arbitrarily in the packet network.But, under the resource release condition, need after user terminal 1 or communication counterpart terminal 2 have been received and dispatched grouping, to be provided with according to confirming.

Comparing section 5 has the function of Memory Reference time.In addition, comparing section 5 has the data of sending here according to measurement section 13 or 13 ', with time of not transmitting-receiving grouping with the function that time of pre-stored compares, also have after the time of not receiving and dispatching grouping surpasses fiducial time function with its notice instruction unit 6.

Instruction unit 6 has the information of sending here according to comparing section 5, indicates the release portion 12 of each node 7～10 to carry out the function that resource discharges.

Each node release portion 12 has the indication of sending according to instruction unit, discharges the interior resource of net that its user utilizes.

In addition, instruction unit 6 and comparing section 5 can be implemented in node or other the interior intranodals of net that form packet path.

Explanation communicates the operation of setting again effectively in the packet communication network under Fig. 5 structure below.

Measurement section 13,13 ' is measured each user's grouping reiving/transmitting state.Its result is delivered to comparing section 5.In comparing section 5, more not the time and the fiducial time of transmitting-receiving grouping, after having certain greater than fiducial time the state of sending here from measurement section 13 or 13 ',, resource is discharged the release portion 12 that indication sends to each node 7～10 from instruction unit 6 then as overtime.The resource release portion 12 that receives this indication just discharges the resource of this node.

After resource discharges fully in the net, when requiring the grouping transmitting-receiving, utilize resource idle in the net to communicate setting again subsequently.Like this, under the state that resource does not discharge fully in net, promptly utilize idle resource, compare, at this moment just do communication easily and set again, and can newly be designed to the state of temporary transient reserve resource with communicating the general user who sets again.An example that is used for realizing the packet communication web frame of above-mentioned purpose is shown in Fig. 6.Among Fig. 6, except that the network function of Fig. 5, still newly be provided with department of resource management 11.

Among Fig. 6, so-called resource situations such as the utilization rate of resource, behaviour in service, use user, User Status in department of resource management 11 monitors regularly and nets.According to this situation, it is the time of the resource reserved state of unit that department of resource management 11 measures with user.

Measurement section 13 and 13 ' is that each user's grouping transmitting-receiving is measured, and gives comparing section 5 with relevant result.More do not receive and dispatch the time and the fiducial time of dividing into groups in comparing section 5, after having a side in the state that measurement section 13 or 13 ' is sent here greater than fiducial time, then as overtime, conversion control in department of resource management 11.

Department of resource management 11 is connected with each node in the net, often the monitoring resources situation.With user is that the resource retention time is measured by unit, and measured time and fiducial time are compared, and can change resource status according to the time.Owing to possess in the net department of resource management with above-mentioned functions arranged,, communicate again and set so can discharge resource effectively stage by stage.

When transforming to control from comparing section 5, department of resource management's 11 energy instructs node 7～10 at first place reserved state with resource.State transition diagram among Fig. 7 has generally shown the stage control of resource in the net.

Department of resource management 11 both can place same intranodal also can place different intranodals with comparing section 5.In the structure of Fig. 6, illustrated by management department 11 and sent the indication of measuring the resource retention time, and under the structure of Fig. 5, also can make comparing section 5 and instruction unit 6 have such function, carry out the management of resource status in respect of time.

Utilize the state transition diagram of the User Status of packet communication network now by showing of Fig. 7, the work of the packet communication network with structure shown in Figure 6 is described.In the following description, the expression various states of user in net shown in Figure 7 in ().

Be to utilize packet communication among Fig. 7, then in Packet Based Network, require communication setting not communicating the user of setting (S31), communicate setting (S32).Communication setting is different because of the structure of net, but communication setting method is then irrelevant with form of implementation, omits its description at this.

Now, resource communicates when setting in utilizing net, also VIP user can be set outside the general user.VIP user can guarantee that preferentially resource communicates setting in net, this resource then be other users about, can continue to guarantee when VIP user removes communication setting.

When being provided with VIP user, can be by general user or VIP user from communication setting state (S32) change state.If the user is VIP user, the resource that this user guarantees is set (resource stationary state: S33) with fixing.If the user is the general user, its resource becomes grouping delivery status (S34).

When transmitting-receiving was not divided into groups under grouping delivery status (S34), its user became the state that is called invalid reserved state (S35).The user that the time of continuing in this state continuation surpasses under situation fiducial time becomes the state that is called common reservation stand-by state (S36).

Measurement section 13 and 13 ' is measured this invalid reserved state, then measurement result is delivered to comparing section, relatively the continuation time and the fiducial time of this invalid reserved state, above after fiducial time, promptly places management department 11, as common reservation stand-by state.

The user who becomes common reservation stand-by state (S36) can give many users the right to use of the common common reservation of resource that uses.Under this state, when this user receives and dispatches when requiring, this user is just identical with the general user to utilize the resource that discharges (free time), except that this utilizes the right of common reservation of resource in addition, can reset circuit more reliably than the general user.

Common reservation of resource can keep certain quantity by network in advance, can press the increase and decrease of situation shown in each example according to the resource behaviour in service of common reservation stand-by state.

When the user that (example 1) keeps stand-by state jointly increases, increase common resource.

When the user that (example 2) keeps stand-by state jointly discharges the resource of common reservation stand-by state, reduce common resource.

The user that (example 3) keeps stand-by state jointly uses the resource of common reservation stand-by state and becomes when dividing into groups delivery status the minimizing common resource.

When common resource being divided into two above grades, can carrying out the common resource usage license by relative importance value, and under the urgent state of resource, price differential can be set further between the user of stand-by state according to the user.

Have again, for example basically or the user who does not communicate fully can resource management not carry out yet.Standby resources is all discharged, and when having had the grouping transmission to require, identical with new user, by guarantee resource from the resource of free time, dwindle the redundancy reservation amount of common reservation of resource.

If when sufficient resource has been prepared in user's requirement, resource management also can be simplified by network industry department, skips stand-by state, converts directly to the resource release condition from invalid reserved state.

Path as directly enter resource release condition (S37) from invalid reserved state (CS35) is shown among Fig. 7.

Resource release condition (S37) are from invalid reserved state (S35) directly, or from common reservation stand-by state (S36), transform to the state when surmounting fiducial time as previously mentioned.The space resources that Any user can both be utilized after resource discharged fully and becomes in the net.Then, identical with new user when transmitting-receiving requires, utilize the interior idling-resource of net again and the rerouting path.

What this must consider be, after the user of transmitting-receiving grouping increases, the resource allocation methods when resource mixes in the net.

Fig. 8 shows the state the when resource in bright certain net mixes gradually.Show bright control example when common resource is divided into two-stage (level A with level a B) among Fig. 4.

Fig. 8 A shows bright when having idling-resource, and at this, resource communicates when setting in the general user utilizes net, is to use the interior idling-resource of net basically.In the situation of Fig. 8 A, the user who keeps stand-by state jointly can utilize idling-resource, keep any in the standby resources jointly communicates setting.

Fig. 8 B and Fig. 8 C show the bright idling-resource that do not have, and common reservation of resource amount turns back to the situation that but has accessible degree enough and to spare amount under the delivery status of dividing into groups the common user of reservation, and (Fig. 8 B is the situation that enough and to spare is arranged with respect to level A and the common reservation user of level B, and Fig. 8 C is the situation that enough and to spare is only arranged with respect to the common reservation user of level A.In Fig. 8 B and 8C, general user becomes busy condition.

In Fig. 8 B, the user of level A can use the common reservation of resource of grade A, and the user of level B can use the common reservation of resource of grade A and level B.Among figure C, the user of level A becomes busy condition, but the user of level B allows to guarantee the resource from common reservation of resource.

According to Fig. 8 C, utilize the user of resource in the net to increase more, as Fig. 8 D, general user and common reservation user then are in and use state of resources fully, when the user proposed grouping transmitting-receiving once more and requires, no matter this user is general or common the use, resource can be idle become before " busy condition " in the net, and in change to that resource is idle in the net and form, just can utilize in the net resource to divide into groups to receive and dispatch.

Having treated as Fig. 8 D like that completely during the state of " busy condition ", from utilizing the user of grouping, is temporarily discharged resource (communication setting releasing) as can be known.

Wish to have the user that can receive and dispatch the environment that divides into groups usually to become VIP user's suitable application area.

Like this, in packet communication network,, also go for the packet communication (mobile packet communication net) in the mobile radio communication for control with communication resource reserved state.This example illustrates with Fig. 9.Feature as mobile radio communication is that the terminal that has a side user at least is transportable, is characterized as the center with this below and describes.

In the mobile packet communication net of Fig. 9, the user who keeps stand-by state (referring to the S36 of Fig. 7) jointly shifts to other places, below just must communicate setting again, also the situation of the resource that promptly must guarantee again in mobile destination describes.At this moment, even the resource that mobile destination is guaranteed also can use in mobile destination.

In mobile communication Packet Based Network shown in Figure 9, add the structure of packet communication network shown in Figure 6, even when the user has moved on in other sub-districts, also need to be used for the structure of management resource.The management of resource is undertaken by department of resource management 142 and department of resource management 243.

In Fig. 9, when user terminal 41 moved on to the sub-district (not shown) in zone 254 by 144 sub-districts, present zone (not shown), the situation that user terminal 41 will move to regional 245 sub-districts sent the department of resource management 243 (S52) that is managing zone 245 to.This for example be from the base station (not shown) that constitutes the sub-district through service control device (SCP: not shown), carry out with respect to the net interior nodes at department of resource management 243 places.Department of resource management 243 is connecting and is managing regional 144 departments of resource management 142.Therefore, (S53) can be sent out to the information of relevant user terminal 41 ' from department of resource management 122 in department of resource management 243, and this information is write (S54).Resource (S55) in Resources Department's management 243 is guaranteed to net according to user's information is arranged again.Be the resource that non-existent user guaranteed in department of resource management's 1,2 release areas, and delete its user profile (S56).Have above-mentioned functions by using in the net, can determine to discharge the interval of resource.

Above-described repertoire can be arranged at node arbitrarily.

By aforesaid operations, can effectively utilize the resource in the mobile packet communication net.

The communication that Figure 10 illustration is connected the same packet communication network of fixedly packet communication network (comprising above-mentioned mobile radio communication) among Fig. 5 or Fig. 6.At this moment, become the node at measurement section 13 ' place with the node 4 of the coupling part of other networks.

Measurement section 13,13 ' is measured the byte number of transmitting-receiving time, the time of transmitting-receiving and the grouping of grouping in user terminal 1, and the time of measuring is sent to comparing section 5.Comparing section 5 is pre-stored with fiducial time, with its with the grouping not the transmitting-receiving time ratio.The transmitting-receiving time is not about to this situation notice department of resource management 11 above fiducial time when this.Department of resource management 11 according to this information of sending here, be instructed in each node and discharge resource.Each node 7,8,9,10 promptly discharges resource in the net that its user utilized according to this indication

(communication setting)

The program of communication setting is owing to adopting common setting program, so omit its explanation in the relevant net.The user has carried out communication setting and has promptly become the communication setting state.Provided communication path (1～3～7～8～9～10～4～2) among Fig. 6, often become and to receive and dispatch status of packets (then being not receive and dispatch status of packets still) from user terminal to the communication counterpart terminal.

(being transformed to the communication reserved state)

Measurement section 13 in the net or 13 ' is measured the service status of user's packet communication, and relevant data is sent to comparing section 5.

Comparing section 5 compares and measures the grouping that portion 13 sends here and does not receive and dispatch time and fiducial time.Be that the fixed value of being scheduled to for example is " 10 minutes " fiducial time, and prestoring is stored in the comparing section 5.When user's grouping not the transmitting-receiving time surpass 10 minutes this fiducial times, comparing section 5 is about to this result notification department of resource management 11.

When resource discharged stage by stage in will netting, department of resource management 11 monitored state of resources in the net in advance, after resource has provided and discharged indication in learning the net that certain user is guaranteed, was about to this resource status and was transformed to common stand-by state.Under this state during, can use and net the common resource that interior idling-resource or user guarantee and communicate setting when above-mentioned customer requirements transmitting-receiving grouping.When this user does not continue the grouping transmitting-receiving, transforming to stand-by state after 10 minutes, department of resource management 11 just discharges this resource fully.Carry out above operation repeatedly, just can effectively utilize resource in the net.When not carrying out the management stage by stage of resource, promptly carry out the release of resource by the structure of Fig. 5.

Describe in mobile network user's the invalid reserved state control program of resource in the net in detail according to Figure 11 below.

(network configuration)

Figure 11 shows mobile network's packet communication network.In Figure 11, DTP is user's a packet communicate terminal 71, and ADP is a connection adaptor 72, and MS is a travelling carriage 73, and BS is a Radio Basic Station 74,75, and MSC is a board 76～80, and SCP is a service control device 86.Mobile packet communication net of the present invention be in existing mobile packet communication net, add measurement section 82,83,84,85 and relatively with instruction unit 87 as unexistent new node in this net.

Base station BS174 is with respect to sub-district (so-called sub-district is a radio areas) 120, and base station BS275 provides radio route with respect to sub-district 221.Board MSC176, MSC277 accommodate base station BS74, BS75.

Board MSC378, MSC479 carry out relaying to MSC176 and the concentrated information of MSC277.Board MSC580, MSC681 have the gateway function with external network.This is identical device to each board MSC on the one hand basically carrying out information exchange functions, but according to the allocation position in the net, can be used as custom system, relay system, gateway system switching station.

A plurality of travelling carriages can be accommodated, be compiled to base station, a plurality of base stations can be accommodated, be compiled to the custom system switching station, a plurality of custom system switching stations can be accommodated, be compiled to the relay system switching station, and a plurality of relay system switching stations can be accommodated, be compiled to the gateway system switching station.In addition, the custom system switching station can compile base station arbitrarily.

Service control device SCP86 storage is used to serve the user profile of control and the positional information of travelling carriage etc.In service control device SCP, include department of resource management.Department of resource management is with respect to the information of used resource situation in the concentrated current service of each user.

Measurement section 81～84 and shown in Figure 5 identical relatively and in the function of instruction unit 87 and the relevant fixedly packet communication network.

(communication setting)

Communication setting program in the net is with aforesaid identical.By this setting, in Figure 11, established communication path from user terminal to other fixed networks, mobile network, become the state that whenever can divide into groups to receive and dispatch.

In this supposition, communicate by the path of terminal D TE～connection adaptor ADP～mobile station MS～measurement section 1～base station BS1～board MSC1～board MSC3～board MSC5～measurement section 2～other fixed networks and mobile network (71～72～73～82～74～76～78～80～84～88).

(transforming to the communication reserved state)

Transform to identical in communication program of reserved state and embodiment 1 situation.Measurement section 1 or 2 (12 or 14) in the net is measured the situation of user packet communication amount.

At this, when the user continues its invalid reserved state, the data that comparing section 87 is sent here according to measurement section 1 or 2 (82 or 84), the time and the fiducial time of dividing into groups to receive and dispatch with respect to this user.According to this result, consider degree of priority by instruction unit, each node (74,76,78,80) in netting is sent conversion user's the indication (function that is equivalent to department of resource management 11 among Fig. 2) of guaranteeing to net interior resource status.Transform to stand-by state in view of the above, and then to release condition.When this user has had the grouping transmission to require, then according to concrete situation rerouting circuit.

At this, the packet communication of mobile network and fixed network a great difference arranged because user terminal moves caused transfer, can change communication path.

(the communication reserved state after the transfer)

When the user by invalid reserved state former state when moving in other districts, for example in Figure 11, user terminal 120 moves on to unit 221 from the unit.Suppose the communication path of setting is at this moment got as terminal D TE～connection adaptor ADP～mobile station MS～measurement section 3～base station BS2～board MSC2～board MSC4～board MSC6～measurement section 4～other fixed networks and mobile network (71 '～72 '～73 '～83～75～77～79～81～85～89) as extreme example.Nature, the node structure in the Home Network and the annexation of extranets, according to mobile subscriber's amount of movement what, change is limited to necessary communication path, node.

Under the delivery status and invalid reserved state of grouping, by common transfer processing, the resource that communicates is guaranteed and is set, and under stand-by state, then by the following stated, continue to keep resource management status (but when carrying out aforesaid common reservation pipe resource management, the continuation of omitting the resource management status of node).

To send each node (75,77,79,81) that includes the new communication setting in transfer destination ground to based on the standby requirement of resource of the user profile of management in the Service Management device 86, guarantee the resource of mobile subscriber in the node of mobile destination.

Simultaneously, discharge the standby resource of moving source.Nonetheless, locate to still have can not guarantee to satisfy the resource of its user institute tool condition the time at each node (75,77,79,81), countermeasure at this moment has:

1. with the mobile subscriber's of mobile destination rank downward modulation, in the hope of guaranteeing resource.

2. when the node place of mobile destination forms the resource of abundant free time, as the standby resources of expectation, the resource during in the hope of the state of guaranteeing to guarantee.

3. with above two kinds of situation combinations, in turn as standby, have as expectation inadequate according to the share that can guarantee.

4. try to achieve essential stock number at last.

According to above-mentioned steps, can be in the resource while that try hard to effectively utilize in the net, provide can follow the user move due to the resource management of change of communication path.

Describe the aforesaid control of determining by fiducial time below in detail.
